A really good story, and well-researched and detailed. Not every day you get a “very interesting life” story that's also a “serendipitously frequently in the background of historical events” story. I really commend the author on writing such a long book that just stays interesting the whole time.

Interesting, well-written and unusually structured in a unique way that WORKED.

Lots of good advice in a concise package, but not necessarily anything I'd never heard before. Recommended overall - it never hurts to be reminded of good ideas you “already know” but aren't using because you forgot

Well-paced and told alongside historical context for those of us who are not experts, plus an engaging cast and story

I expected it to be a little dull, but as an enthusiast wanted to read it anyway. I was totally mistaken, it was extremely well-paced, covered large events as well as interesting anecdotes, and included a great breadth of information.

The majority of the information is in the minority of the text. It suffers from constant restatement of the author's thesis that humankind sees underground pursuits as hell-like, and relies heavily on the reader's existing knowledge of the topography of London.

Sort of a cerebral beach read. Mostly interesting trivia, centered around the theme of “we don't even really know anything”. A satisfying thesis for scientists like me.

Page-turning, obviously embellished but miraculously tolerably so. The middle is very drawn out and loses focus while adding a bunch of characters. Still worth a read.

I friggin loved this book. It goes from zero to creepy-as-hell IMMEDIATELY, and then is really well paced throughout. The author brings in good supporting information at every turn, and when he finally draws his conclusion, he's not bombastic about it.

Page-turning story, well contextualized without being ruined by meandering tangents. Definitely recommend.

Very interesting guy, book moves along at a great pace and is just the right length. I was initially avoiding the book because I thought it would be just factoids about the museum, but it was actually a very interesting look at the dawn of medical education in the US.

Good book, bad mystery
